To all 'william it may con/Jem f Be it imown that li, RALPH D. Moen' "i, :f1 citizen of 'the United States, residing at Lex ington, in the county oif @aviation and State of Nol'tli Caroline, lewe invented. new emi useful improvements in Computing-Pumpe, of which the following is e specification.

This invention relates to improvements in computing pumps.

The obgect olf the invention ie to provide e. pump of this clim'atctet in which the' amount of liquid. (leliveietl may be quickly and accurately eletemiined Without loes.

Another object ie to povicle e pump in which the Cost of the amount delivered may be correctly determined.

Otherolijeete and. edlvetnteges of the tie- `vice will appear :from the :following` cieeeiip tion when teken, in connection Witli the eceompenying diznwinge. v

ln the mwinge; 1 Fignfe'l ie e eide elevation oit e. pump con. structefi in accoi'dence witl my invention..

i iii e vertical eet View oit time Fig. i w en enloig'. detailed View one of the en 'port i, seid support having connected thereto e supply pipe 5. This pipe adapted to enter a Suitable ieeeptecle containing; the liquid to be dispensed. A 1telve 6 controle the flow of the liquid. from this pipe into the een teinei' and this veli/e ie .tutoif nie in fiction as will appear i'i'oin the following description.

Located within the containef is, e pipe 8, said pipe terminating Within e eliort die tance oi tlic upper end of this: ,,cntaine1r, and. having its oppoeite eml connected by means of a. .ialve 9 with e, pipe l0 leading into n pair 0l suction umps Ill. These Suction pumpe may be o any preierretl vconstruction and While there is shown in the flrziwings two of these plunps it is of course uncleietootl Specification of Letters ietent.

that one or more .may be' employed. As

shown these pumpe are connected together` by menne oit' their piston iod 19. and are op erateti. by :i omni?. l5. .tiny suitable connes tion between the eienli; 13 :incl the pieton reels mi the pumpe may be employed. In ad dition the telve 9 wl'iicn ie eontrollcd by one ont time pumps eimiieif telve lll ie provided for the otliei pump. The object oi theee pumps is to Witltifew air from the confteinei' l and censite zt veenum or partialy *mem/im tlevfein in Geiler to lift the valve 6 and draw lthe liquid nioni. the receptacle into the container through the pipe 5'. The pumpe iii me preeieiaiy eonteinedwithn n. wooden, casing i5 ceeiied by tile member' -l and pipe 5. l pipe i6 is` in eommunication with tile eonteinei: i., in o'fler to deliver iiqnid tlielfreii e. suitable valve 17 contro]r ling the i'iew ont liqni from this pipe. A pipe i8 eoimeets the pie 8 anc' the valve 17, outlet poet 19 being provided in E@ein the container l which creates tiieiem Wnleli causes the valve 6 into eie eontziinei' this ope-ration ..-o il tlic liquidi 'has reached e pnetieteiinineti. point. For inetence if vine mii is eoltl et the ireteost 25e per gallon anni it ie tleeii'efl te purchase 15e worth, iiqnitl is; eilowecl to rise until it i'eaches 'the ggietluation opposite l5 under the column 25 ntrthe top, when the valve 17 is' opened. The opening ei this valve destroys the vecuuni through the medium ci the branch pipe i8 enti. time outlet i9, immediately 'caustiie valve 6 to eeen; enel cutting off the ilow of liquid through tlie pipe 5. rihe opening of the vaine li in addition to destroying the mennen delivers the liquidi contained witiiin eon'teineif.

lli' lille the inventionY is Shown as applied to e. penne meneuring vinegzii it is ot course 'eppxiient that it could. be need foi measuring liquide ofi any character, it being only neceese, 'y to ineke the 'giednetions conform with the liquidi. to be sold.

All of 'the pants oit' the device that are in Conta/et with "the liquid ere formed either of in tee epeiittion. ofthe invention adi is Steel frein its. seat end liquid de' wood or of glzise, that there will be no i (lai-nger oi' met er eoi'ioillng. Ail of the pipes:

Various changes in the form, operation and minor details of construction muy be mede Without departing from the Spirit or sacrificing any of the advantages of the `invention.'

A computing 'pump comprising-4 a, container formed of transparent material and having gruduations thereon, a supply pipe communicating with the'bottom of the c0n miner7 means for creating e vacuum within the container, an enlargement formed in me upper end of the supply pipe to provide u chamber 0f greater diameter than the bozze the juncture of said bore and chamber deining 2e valve seat, a bail valve normally positioned upon said seat and Mfted therefrom by the vacuum, a discharge valve communcating with the interior of said cham ber, and a ipe extending across the top of the valve @gember above the ball valve und communicating with the disc'iarge 'valve for destroying the vaeuum am?. permitting the valve te seat.

In testimony whereof I my signature.
